S. application sequence number 11/318 of " the Multiple RadioUsage in a Wireless Communications Device " by name that submitted on December 28th, 2005,581 and require its priority, the full content that is incorporated herein this application as a reference.
Technical field
The present invention relates to radio communication.More particularly, the present invention relates to by the employed technology of the equipment with many wireless access.
Background technology
Wireless communication technology is just becoming very generally so that the local solution that connects to be provided.For example, the equipment that has occurred to provide the wireless network of some types to connect.
Bluetooth has defined and has been intended to originally as the alternative short distance wireless technical of cable.Bluetooth can be used to create self-organizing (ad hoc) network of a plurality of equipment (being also referred to as terminal equipment).One in these equipment is called main equipment, and other equipment are called slave unit.Slave unit can be communicated by letter with main equipment and communicate with one another by main equipment.Equipment is operated in the 2.4GHz radio band that the general service of using for industry, science and medical treatment (ISM) is reserved usually.Bluetooth equipment is designed to find other bluetooth equipments within its communication range and finds the service that they provide.
Ultra broadband (UWB) provides the emerging wireless technology of higher data.Present FCC rule allows 3.1GHz to the communication objective UWB transmission that is used between the 10.6GHz frequency band.Yet for these transmission, spectral density must be under-41.3dBm/MHz, and employed bandwidth must be higher than 500MHz.
There is the multiple UWB transmission technology that can satisfy these requirements.A kind of common and practical UWB technology is called impulse wireless access (IR).In IR, use the short base band pulse that separates by the gap in time to transmit data.Therefore, IR does not use carrier signal.Than traditional continuous wave radio, these gaps make IR less be subjected to the influence of multipath transmisstion problem.The RF gating is the IR of particular type, and wherein impulse is the RF pulse through gating.The pulse of this process gating is the sine wave that carried out mask in time domain by the certain pulses shape.
Another UWB transmission technology relates to OFDM (OFDM).In OFDM, single reflector is launched on several different orthogonal frequencies.OFDM uses the conversion such as fast Fourier transform (FFT) and contrary FFT (IFFT) to transmit information with High Data Rate.
IEEE 802.15.4 is another wireless communication technology.Especially, IEEE 802.15.4 is the standard by international IEEE (IEEE) exploitation.This standard is called " WirelessMedium Access Control (MAC) and Physical Layer (PHY) Specificationsfor Low Rate Wireless Personal Area Networks (LR-WPAN) ".IEEE802.15.4 allows equipment (fixing or move) formation short distance self-organizing network, and equipment can communicate by this network.
Radio Link according to IEEE 802.15.4 can be operated in 3 frequency bands.Especially, this standard provides the 20kb/ data transfer rate of second, the data transfer rate of 40kb/ second is provided in the 928MHz frequency band and the 250kb/ data transfer rate of second is provided in the 2.4GHz frequency band at 902MHz in the 858MHz frequency band.This standard also allows to create self-configuring, multihop network topology.IEEE802.15.4 is characterised in that flexibly: its permission equipment and other wireless device binding operations such as wireless lan (wlan), WiFi, bluetooth.
ZigBee is another emerging wireless communication technology.ZigBee provides a group communication protocol, and this agreement is designed to use based on the less low-power digital wireless access at the IEEE802.15.4 standard of Wireless Personal Network (WPAN).These agreements provide the establishment of low data rate self-organizing and grid network.Such network uses direct sequence spread spectrum (DSSS) transmission in the ISM frequency band.The ZigBee network is a target with the low-power consumption, and the equipment that makes can rely on the battery-operated long time period.The ZigBee network generally includes single ZigBee Mediation Device.In addition, ZigBee provides complete function device (FFD) and simplifies function device (RFD).The software of RFD needs less relatively memory space.
The special interest group of bluetooth (" Bluetooth SIG ") is the employer's organization from the industry-by-industry member that is promoting the blue tooth wireless technology development.At present, Bluetooth SIG is devoted to the discussion about the equipment that can use bluetooth and UWB both techniques.In fact, BluetoothSIG is also considering to adopt the UWB communication technology as " High Data Rate " bluetooth.
From the angle of agreement, such consideration relates to the use of the specific physics of UWB (PHY) layer and media interviews controls (MAC) layer.Yet some upper-layer protocol will use bluetooth host protocol layer (being called the BT host stack).
Existing bluetooth host control interface (HCI) provides the interface between current BT host stack and the BT radio access module.Envision existing HCI at the interface that need not to provide under the situation of substantial modifications between BT host stack and UWB MAC and the PHY layer.Therefore, single HCI will provide traditional bluetooth to communicate by letter both with UWB.
Yet, in the single HCI solution of exploitation, need to overcome some obstacle.For example, an obstacle relates to the use that connects handle (handle).Connecting handle is the identifier that indicates the wireless connections of being created by radio access module (for example by PHY layer and MAC layer).When creating wireless connections, radio access module will connect handle accordingly and return to the BT host stack.At present, the negotiation of between host stack and wireless access, not using about identifier.Therefore, if host stack is cooperated with a plurality of wireless access, then will produce conflict, wherein different wireless access uses identical connection handle.
Therefore, need provide technology with a plurality of wireless access binding operations.In addition, need prevent the technology of conflicting between a plurality of wireless connections.

Especially, Fig. 3 is the block diagram with the similar equipment framework of the framework of Fig. 1.Yet in this framework, wireless access segmentation 106 comprises connection handle discrimination module 302.This module is operated as the intermediary between radio access module 108 and the HCI 104.
In case radio access module 108 has been assigned connection identifier (CID (for example, bluetooth connects handle), radio access module 108 will begin to send at it middle this identifier that uses of information (for example, HCI grouping) of main frame 102.
When specific radio access module 108 receives the connection identifier (CID of being assigned for the first time (for example, in the HCI grouping), discrimination module 302 is stored in the identifier of this identifier as radio access module 108 current uses in the mapping table 304.Whether the identification module 306 in the discrimination module in addition, 302 is determined according to mapping table 304 that this identifier is current and is just used by any other radio access module 108.
If the assignment module 308 in the then discrimination module 302 is assigned standby connection identifier (CID (for example, bluetooth connects handle) for this connects.This standby identifier will use and be connected with this in information (for example, HCI grouping) that corresponding wireless access that is transmitted to main frame 102 by discrimination module 302 initiates.In addition, this standby identifier will be used in the information (for example, bluetooth HCI grouping) that it sends by the HCI 104 corresponding to this connection by main frame 102.As shown in Figure 3, conflict discrimination module 302 comprises communication module 310, and it is handled with this type of of radio access module 108 and main frame 102 and communicates by letter.
Therefore, conflict discrimination module 302 is carried out the packet switched operation.This relates to the connection identifier (CID of replacing in the information of transmitting by HCI interface 104.Here explain this type of packet switched operation with reference to following at the exemplary map table 304 shown in the table 1.
| Radio access module | The connection identifier (CID that radio access module uses | The connection identifier (CID that main frame uses |
| 108a | 0x0001 | 0x0001 |
| 108b | 0x0001 | 0x0002 |
| 108c | 0x0001 | 0x0003 |
Table 1
Corresponding relation between mapping table 304 storage radio access modules 108 and the main frame 102 employed connection identifier (CIDs.Therefore, the every row in the table 1 is corresponding to specific radio access module 108.For every row, table 1 comprises first entry, and it indicates corresponding radio access module 108 employed connection identifier (CIDs.In addition, every row comprises second entry, and it indicates the connection identifier (CID that main frame 102 is used for corresponding connection.
Therefore, according to various aspects of the present invention, the clauses and subclauses of table 1 show the mode that manages conflict.More particularly, in table 1, each radio access module has used identical connection identifier (CID (0x0001) at its connection.Yet specified as discrimination module 302, each during main frame 102 connects at these connects uses unique standby identifier (0x0001,0x0002 and 0x0003).
When main frame 102 transmissions comprised the message of identifier, discrimination module 302 was inquired about this identifier in mapping table 304.Based on this, discrimination module 302 is determined the identifier that should use when this forwards being given its corresponding radio access module 108.Should determine and can disclose: the message that receives comprises the standby identifier that needs are replaced with the identifier (conflict identifier also promptly) of corresponding radio access module 108 appointments.Alternatively, this is determined and can disclose: the message that receives comprises and respective wireless access module 108 employed identical identifier.In this case, need not before message is sent to radio access module 108, identifier to be replaced.
In addition, conflict module 302 is carried out the time-division distribution between radio access module 108.This provides particular time interval, carries out the HCI communication at each radio access module in this time interval.By such distribution, radio access module 108 can not use main frame 102 at one time.
Fig. 4 is the flow chart that shows the exemplary operation of discrimination module 302 according to embodiment of the present invention.As shown in Figure 4, this operation comprises step 402, and wherein discrimination module 302 receives connection identifier (CID from one of radio access module 108.This connection identifier (CID is assigned by radio access module 108, and the wireless connections of being set up corresponding to this radio access module 108.
Next, in step 404, discrimination module 302 determines whether the connection identifier (CID that receives is identical with the employed any connection identifier (CID of other radio access modules in step 402.If then operation proceeds to step 406, otherwise operation proceeds to step 414.
In step 406, discrimination module 302 is assigned standby connection identifier (CID for the connection identifier (CID that receives.In addition, in step 408, the corresponding relation between discrimination module 302 these standby identifiers of storage and the connection identifier (CID that in step 402, receives.This step can comprise corresponding relation is stored in the mapping table 304.
In step 410, discrimination module 302 is used standby connection identifier (CID when exchanging the information that is connected about respective wireless with main frame 102.And in step 412, discrimination module 302 is used the connection identifier (CID that receives in step 402 when exchanging the information that is connected about respective wireless with radio access module.
As mentioned above, when the connection identifier (CID of having determined to receive in the step 402 in step 404 is different from any other employed connection identifier (CID, execution in step 414.Therefore, in step 414, the identifier that discrimination module 302 uses this to receive when exchanging the information that is connected about respective wireless with main frame 102.Equally, in step 416, discrimination module 302 is used the connection identifier (CID that receives when exchanging the information that is connected about respective wireless with radio access module 108.
Connecting handle discrimination module 302 can realize in hardware, software, firmware or its combination in any.For example, in execution mode, discrimination module 302 is embodied as the middleware of between the software of the software of HCI 104 and controller 110,116 and 122, operating.The form of this middleware and software can be a computer program, comprise record computer program logic or program code on it computer usable medium (for example, memory and/or various light and storage medium electromagnetism), to be used for the supporting processor of computer system or equipment to carry out technology described here.
Other method of the present invention comprises new information or the order of using the distribution that relates to connection identifier (CID (for example, connecting handle).With reference to the framework of figure 1 and Fig. 3 this method is described.Yet this method can further together be used with other frameworks.
In the method, main frame 102 receives from the connection of radio access module 108 and sets up request.In response, main frame 102 sends the approval order to the radio access module 108 of request.This approval order is that connection identifier (CID (for example, bluetooth connects handle) is assigned in the connection of being ratified.Therefore,, avoided the conflict between the identifier, because identifier is assigned by single entity (main frame 102) according to the method.And, if starting, main frame 102 connects (also promptly, not receiving connection request) from other terminations, then can distribute connection identifier (CID by main frame 102.
The block diagram of the exchange that the HCI that Fig. 5 and Fig. 6 show various aspects of the present invention to be provided orders.With reference to figure 1, these block diagrams show the order of exchange between main frame 102 and radio access module 108 (for example, UWB radio access module 108b).These orders exchange by interface (for example HCI 104).
With reference to figure 5, UWB radio access module 108b execution in step 502, wherein, UWB radio access module 108b has received the connection request to create and has sent establishment connection request message (being shown HCI_connection_request_ext) to main frame 102.These connect connection identifier (CID (for example, bluetooth connects handle) and other parameters that parameter comprises suggestion.These other parameters can comprise wireless access identifier and one or more wireless access parameters (for example, power, tuning, data transfer rate etc.).
After receiving this request, main frame 102 determines whether to ratify the connection of being asked.Should determine can be based on various factors.If any connection identifier (CID the conflict whether connection identifier (CID that approval, main frame 102 further determine to be included in the suggestion in the request uses with other radio access modules (for example, radio access module 108a and 108c).If the connection identifier (CID conflict of suggestion, then main frame 102 is that the one other identification symbol is assigned in the connection of being asked.Yet, if the connection identifier (CID of suggestion not with any other identifier collisions, main frame 102 is the identifier that this suggestion is assigned in the connection of being asked.
Fig. 5 shows main frame 102 execution in step 504.In this step, main frame 102 generates and sends to be created bind command and (is shown HCI _ create_connection_ext).As shown in Figure 5, this order comprises one or more connection parameters.Although Fig. 5 is shown response to connection request with this, this order can be initiated by main frame 102.
The establishment bind command that sends in step 504 guides UWB radio access module 108b to connect according to the various parameters of carrying in the message.One of these parameters comprise the connection identifier (CID of being assigned.After receiving this message, UWB wireless access 108b correspondingly connects.Set up in case should connect, UWB radio access module 108b sends connection to main frame 102 and finishes message (being shown HCI_connection_completed_ext) in step 506.As shown in Figure 5, this message can comprise the parameter that comprises in the establishment bind command of step 504.
Bluetooth HCI does not provide the message (HCI_connection_request_ext, HCI_create_connection_ext and HCI_connection_completed_ext) of Fig. 5 at present.Therefore, embodiments of the present invention with these orders as the expansion of bluetooth is provided.
New information or order (and incident) that another method of the present invention provides indication and solves potentially conflicting.For example, with reference to figure 1, be configured or set up connection and notified main frame 102 connections may clash when finishing at radio access module 108.In case set up, radio access module 108 (by HCI 104) will be used for connection identifier (CID (for example, bluetooth connects handle) the notice main frame 102 of this connection.At this moment, main frame 102 can determine this connection identifier (CID whether with other radio access module 108 employed any identifier collisions.
If main frame 102 definite existence conflicts connect, then embodiments of the present invention provide order (for example HCI order) for main frame 102, can not use with the connection identifier (CID of notifying radio access module 108 its distribution.In addition, this order can also provide to radio access module 108 new (non-conflict) connected handle for use.
